1. A method for decoding a menu data segment, the method comprising the steps ofdetecting, within the menu data segment, data corresponding to a plurality of menu items belonging to a menu page;
- extracting from the menu data segment for each menu item of the plurality of menu items at least first data defining whether the menu item is selectable and second data defining whether the menu item has graphic representation data associated;
decoding data corresponding to first menu items to selectable display data, wherein the first menu items are menu buttons and have graphic representation data associated;
decoding data corresponding to second menu items to non-selectable and visible display data, wherein the second menu items have graphic representation data associated; and

Abstract
Optical storage media often contain data structures for a menu suitable for selection of a title, a chapter, a parameter or others. Such menus usually comprise a number of buttons to be displayed, with each button having a state. Possible states of buttons are e.g. “unselected”, “selected” or “activated”. According to the invention, the menu may contain buttons that can be selected through the keys on the remote control, but that don'"'"'t have any images or text associated. This allows creating “invisible buttons” that automatically execute commands upon selection. Further, a sound or sound sequence, e.g. melody or click, may be associated to a buttons state, and may be played back when the button enters this state. Such menu data may be stored e.g. on a Blu-ray disc.
